متن کاملAtomic mass of Li using a Penning-ion-trap mass spectrometer
The atomic mass of Li has been measured using a Penning-ion-trap mass spectrometer to be 6.015 122 795~16! u. The fractional measurement uncertainty of 62.7310 represents a 30-fold improvement over that of the accepted published value. External ion sources were used to create ions outside the cryogenic ~4 K! environment of the Penning trap and an ion-transport beamline was used to deliver ions ...
متن کاملA novel high-capacity ion trap-quadrupole tandem mass spectrometer.
We describe a prototype tandem mass spectrometer that is designed to increase the efficiency of linked-scan analyses by >100-fold over conventional linked-scan instruments. The key element of the mass spectrometer is a novel high ion capacity ion trap, combined in tandem configuration with a quadrupole collision cell and a quadrupole mass analyzer (i.e. a TrapqQ configuration). This ion trap ca...
متن کاملA quadrupole mass spectrometer for resolution of low mass isotopes.
The qualitative and quantitative identification of low mass isotopes in the mass range 1-6 u poses certain difficulties when attempting to achieve the required resolution with an instrument suitable for deployment within a process environment. Certain adjacent species present in the process sample (HT and D(2)) require a resolution greater than 930 to achieve an accurate measurement. We demonst...
متن کاملFirst use of high charge states for mass measurements of short-lived nuclides in a Penning trap.
Penning trap mass measurements of short-lived nuclides have been performed for the first time with highly charged ions, using the TITAN facility at TRIUMF. Compared to singly charged ions, this provides an improvement in experimental precision that scales with the charge state q. Neutron-deficient Rb isotopes have been charge bred in an electron beam ion trap to q=8-12+ prior to injection into ...
